Try to read this for tomorrow's class

I'd like to discuss this in class tomorrow. I know I'm posting it at the last minute. I've been sick. It's an example of a really good feature -- it won a bunch of awards last year -- and I'd like to talk about how it was done and deconstruct it. Thanks. Professor Barker
